Presence of more than two alleles for a gene in a population is referred as

Options

A. Mutant alleles
B. Multiple alleles
C. isoalles
D. Pseudoalleles

Answer

To solve the question regarding the presence of more than two alleles for a gene in a population, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for the term that describes the presence of more than two alleles for a single gene in a population.

2. **Identify the Options**: The options given are:
- Mutant alleles
- Multiple alleles
- Iso-alleles
- Pseudo-alleles

3. **Define Each Term**:
- **Mutant Alleles**: These are alleles that differ from the standard allele found in a typical organism. They do not necessarily imply the presence of more than two alleles.
- **Multiple Alleles**: This term refers to a situation where a single gene has more than two allelic forms within a population. This definition matches the question perfectly.
- **Iso-alleles**: These are alleles that can only be distinguished from normal alleles through special tests. This does not pertain to the number of alleles present.
- **Pseudo-alleles**: These are genes that are closely located on a chromosome and have similar functions but do not refer to the number of alleles.

4. **Select the Correct Answer**: Based on the definitions, the term that correctly describes the presence of more than two alleles for a gene in a population is "Multiple alleles."

5. **Final Answer**: The correct answer is **Multiple alleles**.
